[Model for describing tremor (authors transl)].

Acceleration measurements of lower arm, hand and finger tremor principally contain several reproducible peaks in thier power spectral density function. The transfer function of the system was determined by application of a sinusiodal force with an amplitude of less than 1 p.c. of the maximum isometric strength. For description of the lower arm tremor a closed loop system was proposed combining the vibration of a mechanical resonant system with stochastic forcing and the oscillation of the neuromuscular reflex arc, The elements of this system were analyzed by cros-correlation of elctrical of electrical activity and tremor vibration and by analog computer simulation.
